5 Signs You've Got a Lousy Tax Preparer

With your name on the line, it's important to make sure your taxes are done right.

NEW YORK ( MainStreet) -- Taxes are hard enough without having to deal with a lousy -- or worse, unethical -- tax preparer that could set you up for an unpleasant audit down the line. How do you know you've landed a rotten fish?

According to the Internal Revenue Service, more than 144 million tax returns were filed by individuals in 2010, with gross collections totaling about $1.2 trillion. Professional tax preparers handle about 60% of those returns.

With your name on the line, it's important to make sure your taxes are done right.

With that kind of dough on the line, taxpayers can't afford any mistakes -- but that's exactly what they seem to be getting from tax preparers. A 2006 study by the Government Accountability Office looked at a random sample of 19 tax preparers and found that all 19 made mistakes, including claiming too many exemptions, failing to claim allowable tax credits and missing tax deductions that could have saved them money.

So how do you know that you're risking a raw deal with your tax preparer? If you run into any of these scenarios, keep your guard up and your cash down -- and keep on looking for a licensed professional who knows what he or she is doing:

Your preparer promises a big refund.Any tax preparer who flat-out guarantees a big tax refund may be leading you on -- especially if they haven't seen your financial documents yet. "One of the biggest scams are tax preparers who advertise they can guarantee you the biggest refund before they even look at your tax information," explains Yvette Rebella, a board member of the California Tax Education Council, a nonprofit tax organization.

One potential tactic that results from their promise of a big refund is to juggle the numbers on your tax return to generate the big payout, but that risks an IRS review and bigger problems down the road.

Your preparer doesn't have proper credentials.You can avoid potentially serious issues simply by checking to see if your tax preparer has the correct identification. The IRS recently began assigning Preparer Tax Identification Numbers (called "PTINs"), so if your tax specialist can't provide one, you may be courting trouble by using an unlicensed preparer.
